3 Cla ms (Cl. 123-475) This; inventionillelazt fii flr mpro m ts in automobile Water pumps.

An: object: of. the: invention is to;- pliovide an improved: noneleakin water circula in p mp f r circulating the water-betw en the. water i cketin the cylinder head; or an; au mobile engine n the cooling radiator associated therewith,

Another object of the invention is to provide an improved. for-m1 of? circulating water pump of water cooled internal combustion engines which will have the bearing therefor removed from contact with. the water being rculated,

A further object of the invention is to provide an improved automobile water pump which will be so constructed andarranged that the pump housing or casing may be readily removed without disturbing the fan belt which is used for driving the same, and said pump being supported upon the. top of the engine cylinder head where it may be easily reached for making repairs or adjustments.

Another object of the invention is to provide an improved automobile water circulating pump which will be highly efiicient. in operation, and relatively inexpensive. to. manufacture andproduce.

Other objects will appear as the description proceeds.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is devised and provided an automobile engine I having a cylinder head 2 and a cooling radiator 3 associated therewith.

The cylinder head 2 is formed with a water outlet port or passage 4 through its upper wall,

2. t e annu a ba e flan 5 e nu e-re wa e uma ati hous n is olted t h cylinder head 2 byv means; of the bolts 1 with the ub a rumma t n er a a i me t w t the. water outlet per-t or passage 4;.

n, el w-pirefitti :theme: r e t" reade at itsoppositeends ,9 and t0 willbe screwed upon the upper threaded end ll, ot the. tubular pump c sing 6 and a v rti al hea n l2 willbe su p hr u h the upper wa l of he e bo fitting & .eb aring I 2 Provi ed with. he packn l3 disposed in its upper end portion, being secured in place. by the internally threaded bearing capl-4 threaded uppn the externally threaded upper end L5 of the bearing It.

An elongated screw impeller It provided with a. central shaft H- is rotatably disposed within the pump casing 6; with the. upper end of the shaft H extendin v through the bearing t2, whose packing i3 is positioned above; the water I8 in the pump casing 6v and elbow fitting 8., and is never contacted by the water as it is being circulated.

A spur gear l9: secured.- upon the upper end ofthe shaft H and is adapted to mesh with a smaller spur gear 20 secured upon the upper end of the shaft 2| rotatably mounted between the upper bearing 22 and supporting bracket 23 attached by means of the bolt 24 to the elbow fitting 8, and a lower bearing 25 and supporting bracket 26 which will be attached to the horizontal bearing 21 supported by the bracket 28 upon the top of the cylinder head 2 by means of the bolt 29.

A bevel gear 30 is fixed upon the lower end of the vertical shaft 2| and meshes with a bevel gear 3| disposed upon the rear end of the shaft 32 supported in the horizontal bearing 21.

A pulley 33 is supported upon the front end of the shaft 32 and is driven by the fan belt which extends about the pulley 34 upon the shaft 35 which supports the fan 36, and about the pulley 31 on the crank shaft 38 of the engine I, being the driving means for the fan 36 as well as for the water pump impeller It.

An outlet pipe 39 will be screwed into the threaded outer end 9 of the elbow fitting 8, and a hose connection 40 will be connected between the pipe 39 and the pipe 4| 0n the radiator 3, being secured in place by means of the hose clamps 42 and 43.

From the foregoing description, it will be apparent that there will be no leaking of the water pump possible, as the water line in the pump will be below the packing l3 in the bearin [2 for the shaft ll of the water impeller 16, and therefore the water 58 will never reach the packing 13.

The positioning of the water pump upon the top of the cylinder head 2 of the engine I pro vides for ready access to the same.

From the foregoing description, it will be ap-- parent that there has been devised and provided a highly efiicient form of automobile water circulating pump which will be relatively inexpensive to manufacture and produce.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention. 1

Having described the invention, what is claimed as new is:

1. A water circulating pump impeller comprising a vertically extended pump casing having a base attaching flange, an elbow on the upper end of said casing, a vertical bearing in said elbow, packing therefor above the water line in said elbow, a screw impeller disposed in said pump casing having a shaftformed thereon with its upper end disposed in said bearing, a spur gear on said shaft, a second shaft disposed in parallel relation to said pump casing, a spur gear on the upper end thereof in mesh with the spur gear on said impeller shaft, a horizontally mounted shaft adjacent said second shaft, meshed beveled gears on the rear end thereof and on the lower end of said second shaft, and a pulley on the front end of said horizontal shaft adapted to be driven by the usual automobile fan belt.

2. A water circulating pump impeller comprising a vertically extended pump casing having a base attaching flange, an elbow on the upper end of said casing, a vertical bearing in said elbow, packing therefor above the water line in said elbow, a screw impeller disposed in said pump casing having a shaft formed thereon with its upper end disposed in said bearing, a spur gear on said shaft, a second shaft disposed in parallel 4- relation to said pump casing, a spur gear on the upper end thereof in mesh with the spur gear on said impeller shaft, a horizontally mounted shaft adjacent said second shaft, meshed bevel gears on the rear end thereof and on the lower end of said second shaft, a pulley on the front end of said horizontal shaft adapted to be driven by the usual automobile fan belt, an outlet pipe connected with said elbow, and a hose connection connected therewith and to the usual automobile coolin radiator.

3. In combination with an automobile engine having a cylinder head and a cooling radiator associated therewith, a vertically extending pump casing having a base attaching flange supported upon said cylinder head, said cylinder head being formed with a vertically aligned outlet passage in vertical alignment with said pump casing, an elbow on the upper end of said casing, a vertical bearing in said elbow, packin therefor above the water line in said elbow, a screw impeller disposed in said pump casing having its lower end extending through the bottom thereof and a shaft on its upper end extending throuh said bearing and means for connecting said elbow with the usual automobile cooling radiator, and means for driving said impeller.
